The fact that at least a couple are right suggest that it's more likely to be a case of calling with the wrong names or format rather than that the install was defective. Again, I'd like to look at what attributes are actually named in the module itself, as-installed, on my machine, but how to do that is still a mystery to me.

My earlier attempt to install ImageMagick, v7.0.8, with PerlMagick, in Ubuntu 18.04, along with my attempts to remove it, in order to reinstall Ubuntu's "standard" version, 6.9.7, resulted in silent failure, by which I mean, the reinstall of 6.9.7 did not, completely, succeed, but with no obvious indications of failure.

After finally discovering that SetPixel() was giving really weird results reading .PNG files, I decided to verify that it, really, was set up to read them (it was reading the Get('attribute') data just fine).

Lovely... looks like imagemagick pkg wasn't installed by the pkg manager (apt), but attempts to "install" it said that it was. So I've ruined or at least munged the ability to install the Ubuntu-supported version of ImageMagick.

...Proceeding... I removed and purged the 6.9.7 package and re-installed version 7.0.8 from source.

Running the same "magick -list configure" under 7.0.8 indicates support for a very short list of formats:

% convert logo: logo.gif # WORKED
% make check # FAILED on only two items

FAIL: tests/wandtest.tap 1
FAIL: Magick++/demo/demos.tap 6

Ghostscript is INSTALLED, but my pkg manager does not know about Freetype. [EDIT: I found a pkg called freetype2-demos and installed that on a whim, and reran the make check, with the same two failed results.][EDIT: I found some Ubuntu-specific install instructions, which calls for first installing a kitchen-sink-ful of things which, I guess, "might" be looked for during installation, and one of the things listed was 'libfreetype6.']
